Inclusion criteria

  • At least one year registered with the general practitioner (GP), one year of valid data from the GP, or the date of software conversion (if GP software systems had changed) and meeting criteria for any one of the 4 cohorts as defined.

Exclusion criteria

Exclusion Criteria:

  • rheumatic heart disease
  • congenital heart disease: includes structural defects, congenital arrhythmias, and cardiomyopathies
  • dilated cardiomyopathy (congestive cardiomyopathy

  • carcinoid syndrome
  • intravenous drug abuse
  • fibrotic valvular heart disease
  • pleural/pulmonary/pericardial/retroperitoneal fibroses
  • use of fenfluramine or amiodarone within 3 years prior to date of diagnosis of fibrotic valvular heart disease

What researchers measure

Primary outcomes

  1. Number of Participants With Fibrotic Valvular Heart Disease Per 10,000 Participant-Years of Follow-Up

    Occurrence of: mitral stenosis with insufficiency, other unspecified mitral valve diseases, mitral or aortic valve stenosis, insufficiency, or disorders, multiple involvement of mitral and aortic valves, mitral and aortic valve diseases, unspecified, diseases of tricuspid valve, tricuspid valve disorders, specified as nonrheumatic, pulmonary valve disorders, endocarditis, valve unspecified, endomyocardial fibrosis, endocardial fibroelastosis, other primary or secondary cardiomyopathies, cardiomyopathy, functional and undiagnosed cardiac murmurs, other abnormal heart sounds.

    Time frame: Up to 12 years

  2. Number of Participants With Fibrosis Per 10,000 Participant-Years of Follow-Up

    Occurrence of: idiopathic retroperitoneal fibrosis, occlusion not otherwise specified (NOS) of ureter, diffuse (idiopathic) (interstitial) pulmonary fibrosis, Hamman-Rich syndrome, interstitial pneumonia (desquamative) (lymphoid), fibrosis of lung (atrophic; confluent; massive; perialveolar; peribronchial) chronic or unspecified, pulmonary or pleural fibrosis, abnormal communication between pericardial and pleural sacs, pleural fold anomaly, adhesive or constrictive pericarditis, pericardial fibrosis

    Time frame: Up to 12 years

  3. Number of Participants With Heart Failure Per 10,000 Participant-Years of Follow-Up

    Occurrence of: unspecified acute edema of lung, heart failure, acute pulmonary heart disease, or acute cor pulmonale

    Time frame: Up to 12 years

  4. Number of Participants With All-Cause Mortality Per 10,000 Participant-Years of Follow-Up

    All participants who died independent of the cause to include instantaneous death, death occurring in less than 24 hours from onset of symptoms, not otherwise explained, unattended death and other causes of ill defined morbidity and mortality. Cause of death was coded and classified as either cardiovascular or respiratory.

    Time frame: Up to 12 years
